Ionisation Techniques

To take advantage of the basic laws of physics, the analyte has to be ionised before being introduced into the gas-phase for mass analysis. There are a large number of ionisation methods – many can only be used for certain types of analyte.The links below will send you to pages outlining the basic principles of the most important techniques. The final page is a summary of the types of ions that maybe observed in a mass spectrum.
